The HALO DB-20 is capable of calculating the concentration of a sample after
generating a standard calibration curve or by entering a factor into the system.
The following are the features of this function.
(1) Generation of standard calibration Curve
(a) Up to twenty samples can be measured, and the acquired values are
connected to each other with segmented lines or regression lines
determined by the least squares method for generating a working curve.
(b) Specific standard samples can be measured again to regenerate a
working curve.
(c) A working curve can be regenerated upon deleting specific standard
samples.
(d) Working curves can be stored as a part of measuring conditions. It is
possible to store the curves for a maximum of twenty tests.
(e) Working curve can be graphically displayed on the LCD, and a value at
a desired point can be read by moving the cursor to that point.
(f) Analytical results are displayed on the LCD together with the working
curve. Thus, the results can be confirmed while observing the working
curve.
(g) Working curve can be graphically plotted on the printer.
(h) Working curve can be generated by entering factor values.
(i) It is possible to generate a working curve by 2 - /3 – wavelength
measurement.
(2) Statistical Calculation
This function enables the instrument to acquire mean value, standard
deviation (SD) and coefficient of variation (CV).
(3) The upper and lower limit values of analytical data can be judged.
2.4.2 Wavelength Scan
(1) The highest wavelength scan speed is 3600nm/min. Wavelength ranging
from 1100~190nm can be scanned in a little over 20 seconds even if the
filter and light source are switched over halfway.
(2) Wavelengths can be scanned repeatedly for recording spectra of a sample
that changes with time.
(3) Photometric values can be printed out at the specified wavelength interval.
